Specification of Letters Patent. Patent ed Blay 30, 1916.

Application filed March 8, 1916. Serial No. 82,8991

intermediate portion of the member extending-between the guide or restraining wings 2. The upper forming the lower member of the tooth is bent toform an'elongated loop .5 which fits snugly against the lower or coircayeface of the member 1 and straddling this loop is a yoke 6 adapted to-be held in place by a bolt 7 which extends through the loop and also through the member 1, said bolt being secured in place in any manner desired, as by means of a nut 8..

. It will be Obvious Beitknown that I. HARRY M. Goonrxo,

Attica, in the eolin-t'y of Seneca and State,

of Ohio, have invented a new and useful Spring-Tooth, of which the following 15 a I Thisinventiori relates to a' spring tooth for use in connection with weeders, scarifiers and the like, one of the objects being able' longitudinally, thereby to vary, its degree of flexibility to meet different conditions and which is likewise adjustable longitu'dinalh to compensate for wear.

A further object is to provide a'tooth which can be readily-detached for the purposeof sharpening it.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the com bination and arrangement ofparts and in that when the bolt 7 5 and clamp the loop upon the member 1. Thus the member 8 will be held against longitudinal movement relative to the member 1. Loop 5 prevents rotation'ofth'e member 3. As the point of the tooth Wears tooth member 3 moved downwardly to compensate for the wear. Should it be desired to lengthen the tooth it. ismerely necessary to increase the distance between the end of the member 1 and point i. It will di l d be d be noted that the tooth is curved from one what i l im d ithend to the other and that the upper portion th i it f th inventhereof, which is subJected to the greatest strain, is backed or reinforced by-the. member 1. Member l can be secured to a supporting structure, such as a cross-bar 9 of a frame.

What is claimed is 1. A spring tooth including a relatively scribed and claimed, it being understood the invention herein within the scope of In the accompanying drawings the preferred formof the lnvention has been shown.
